SN54HC151J datasheet by Texas Instruments

SN54HC151J Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN54HC151J?
  The maximum operating frequency of the SN54HC151J is 25 MHz, but it can vary depending on the supply voltage and operating conditions.
• How do I ensure that the SN54HC151J is properly powered?
  To ensure proper power supply, connect the VCC pin to a stable 2V to 6V power source, and the GND pin to a reliable ground connection. Also, decouple the power supply with a 0.1uF capacitor to reduce noise and ensure stable operation.
• What is the maximum input voltage that the SN54HC151J can tolerate?
  The maximum input voltage that the SN54HC151J can tolerate is 7V, but it's recommended to keep the input voltage within the recommended operating range of 2V to 6V to ensure reliable operation.
• How do I handle the enable inputs (E1 and E2) to ensure proper operation?
  To ensure proper operation, the enable inputs (E1 and E2) should be driven with a logic level signal (either high or low) and not left floating. When both E1 and E2 are high, the device is enabled, and when either E1 or E2 is low, the device is disabled.
• What is the propagation delay of the SN54HC151J?
  The propagation delay of the SN54HC151J is typically around 10ns to 20ns, depending on the supply voltage and operating conditions. This delay is the time it takes for the output to change state after the input changes.
